【英文篇名】 Discussion on energy saving of variable frequency chilled and hot water pumps in an air conditioning system 【作者中文名】 沈翔; 王建民; 【作者英文名】 By Shen Xiang~ and Wang JianminShanghai Nuclear Engineering Research and Design Institute; Shanghai; China; 【作者单位】 上海核工程研究设计院; 【文献出处】 暖通空调, Heating Ventilating 定末端压差控制; 最小阻力控制; 水泵; 节能; 【英文关键词】 constant pressure control; constant terminal differential pressure control; minimum resistance control; pump; energy saving; 【摘要】 分析了定扬程控制、定末端压差控制和最小阻力控制三种控制方式,指出定末端压差控制可能导致水泵扬程不足,并且在实际情况下无论哪种控制都不可能使水泵消耗的功率与流量的三次幂成正比。 【英文摘要】 Analyses three control modes—constant pressure control, constant terminal differential pressure control and minimum resistance control. Points out that constant terminal differential pressure control may result in insufficiency of pump pressure, and actually the power of pumps can not be in proportion to the third power of the flow in each control mode.
